Altrmus - Alternative music for Heroes 5.

Could you please tell me how to add music from Heroes of Might and Magic IV? Perhaps there is even a separate mod that replaces the music in Heroes of Might and Magic V with music from Heroes of Might and Magic IV? Simply put, Heroes of Might and Magic IV has the most amazing music, and I would like to hear it in Heroes of Might and Magic V - Tribes of the East 3.1. Thank you in advance.
